The process of investigating and checking a program to nd whether there is an error or not and does
it ful ll the requirements or not is called testing.
• When the number of errors found during the testing is high, it indicates that the testing was good and
is a sign of good test case.
• Finding an unknown error that’s wasn’t discovered yet is a sign of a successful and a good test case.
